Question

the perimeter of a rectangle is 70 meters. the width of the rectangle is 10 meters. how long is the rectangle?

Answer 1

The equation to find perimeter is 2w + 2l, with w = width and l = length. In the problem, we are given that the perimeter is 70 meters and the width is ten meters. we can plug this values into the equation.
70 meters = 2(10) meters + 2(l) meters.
now, we can use algebra to find the length.
70 meters = 20 meters + 2l meters
-20 -20
50 meters = 2l meters
/2. /2
length = 25 meters
hope this helps!
